Michael Carrick says Manchester United teammate Dimitar Berbatov is a one-off.
Carrick is amazed by the ability Berbatov shows in training and in games.
He told manutd.com: "Berba's got the ability to do things that not many people can do. You've seen his goals, some of his skills... a lot of the time at training he does things that are very special.
"Other people can't replicate it. The overhead kick against Liverpool... the way he kicks the ball and plays at his own pace. He almost teases defenders into thinking they can get the ball. Not many people can do what he can do."
